Abstract
This prospective study compares the effect of two viscoelastic agents (Viscoat and Provisc) on an early postoperative
intraocular pressure after phacoemulsification and intraocular lens implantation. The study compares 36 patients
with senile cataract. Intraocular pressure (IOP) was measured by standard Goldmann aplanation tonometry preoperatively
as well as on the first postoperative day, after 24 hours and 1 week postoperatively. The mean postoperative IOP
at first postoperative day in the Viscoat group was 24.2 mmHg and in the Provisc group was 21.2 mmHg. The increase
was significantly higher in the Viscoat group than in the Provisc group but after 24 hours and 1 week postoperatively
the mean IOP was not statisticaly different. The two viscoelastic agents cause equivalent pressure elevation postoperatively.
